DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention concerns a cassette recorder which can record programming automatically after storing data such as the day of the week, the time and the channel.
2. Discussion of the Prior Art
DE-OS No. 33 14 783.3 discloses a videorecorder, in which the cassette is equipped with a bar code that is concerned with various parameters of the cassette, such as the tape length. The bar code is read with an opto-electronic reading device, arranged in fixed location in the recorder, so that it can utilize the movement of the cassette into play-back position for the reading process.
SUMMARY OF THE INVENTION
The object of the present invention is to simplify an input into a video recorder.
The above and other objects are accomplished by the invention in which a cassette recorder and a cassette are used for selectively automatically recording programs based on parameters that have been selected by a user. The cassette comprises a housing having a dedicated area thereon for a user to mark indicia representing parameters to be read by the recorder so that selected programs can be automatically recorded. The cassette recorder includes a reading means for reading the indicia on the cassette and control means for receiving a signal indicative of the indicia and storing it in a memory so that the control means can trigger automatic recording of the selected programs.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention may be better understood by referring to the detailed description of the invention when taken in conjunction with accompanying drawings in which:
FIG. 1 illustrates schematically the housing of a videorecorder with the cassette not yet inserted;
FIG. 2 illustrates schematically the cooperation of the cassette with the opto-electronic reading device;
FIG. 3 illustrates schematically a different arrangement of the table on the cassette for a videorecorder which operates somewhat differently;
FIG. 4 illustrates a further location of the table on the cassette;
FIG. 5 illustrates a markable table on the label; and
FIG. 6 illustrates a modification of the markable table.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 shows a videorecorder 1 with an opening 2 that is closed by a flap 3 that is pivotable around a horizontal axis. On the front side of the recorder 1, a plurality of control and indicator elements 4 as well as a numerical display 5 for the indication of tape length and time of day are located. The videocassette 6 is horizontally insertable by hand into the opening 2 in the videorecorder 1. As the videocassette 6 is placed into the opening 2, the flap 3 is swung open. The videocassette 6 is grasped by a transport device automatically set into operation so that the videocassette 6 is transported first in the horizontal direction and then in vertical direction down into the play-back position. Such a videorecorder having a front loader with elevator is described in more detail in DE-OS 30 31 690.
According to FIG. 2, the videocassette 6 is provided with a label 8 on the housing's outer wall 7. A table 15 is arranged on the label 8. An opto-electronic reading device with a photodiode 9 and a phototransistor 10 is located within the videorecorder 1. For scanning, the photodiode 9 sends a light beam 11 to the label 8 having the table 15; the beam is modulated according to the table 15 and is reflected so that it reaches the phototransistor 10. The phototransistor 10 then supplies the readout signal to the control 12. The table 15 contains a plurality of parameters for recording according to real time or VPS data (VPS=video program system) or for the videocassette 6; these data are evaluated in the control 12 and serve to control various functions in the videorecorder. The control 12 works as an automatic recording device and controls the pickup and the recording of transmissions. The control 12 also controls, for instance, the electronic counter for the numerical display 5 of the tape position, a change-over corresponding to the type of the videocass
