BRIEF SUMMARY
FIELD OF THE INVENTION
This invention relates to a printer for printing a balance or remittance report on a paper roll in an automatic teller machine or the like, and more particularly is directed to a paper roll support apparatus for such a printer which includes mechanisms for resupplying and guiding paper rolls and releasing used empty rolls.
DESCRIPTION OF THE RELATED ART
An automatic banking machine such as an automatic teller machine (ATM) or a cash dispenser is used to deposit or draw money or to make remittance by using a magnetic card like a credit card or a cash card. The automatic teller machine includes a printer for printing a balance or remittance report (called "balance report" hereinafter). The printer usually operates on the thermal transfer recording or thermal recording system, unrolls the paper roll and prints each balance report on the unrolled paper, cuts the paper to a prederemined length, and supplies the balance report to the customer. The paper roll is rotatably seated on a support without a support shaft. Since the paper on the roll is consumed each time the balance report is issued, a new paper roll is set on the support by detecting the residual of the paper roll according to the number of issued balance reports or the reduced diameter of the paper roll, or visually detecting the residual of the paper.
The automatic teller machine including the printer is generally installed in a relatively narrow space, and is required to be compact as a whole. Therefore, the paper roll is usually dropped into the support from above or is rolled into the support from behind.
The paper roll is unwound on the support in the predetermined direction. When it is placed in a wrong direction, the paper roll should be correctly reloaded.
The more frequently the automatic teller machine is operated, the faster the paper roll is consumed and a new paper roll has to be resupplied more frequently. For this purpose, a spare paper roll is also placed beside the main paper roll in use so that the automatic banking service can be offered without interruption.
The automatic teller machine should be not only compact as described above but also be simply designed to facilitate work such as replenishment of a new paper roll or release of a used paper roll.
With the foregoing problems in mind, it is therefore an object of this invention to provide a paper roll support apparatus for a printer which is compact in size, is easy to resupply a new paper roll and release a consumed paper roll, and can issue the balance reports on the new paper roll without interrupting the automatic banking service.
A further object of the invention is to provide a paper roll support apparatus which can easily release a consumed paper roll in a narrow limited space.
A still further object of the invention is to provide a paper roll support apparatus which can reliably support paper rolls and can assure easy resupply of new paper rolls.
SUMMARY OF THE INVENTION
According to a first aspect of the invention, there is provided a paper roll support apparatus comprising: a main paper roll support for rotatably supporting a main paper roll; paper feed unit for unrolling the main paper roll and feeding the paper; a spare paper roll support for supporting a spare paper roll and located behind the main paper roll support; a residual sensor for detecting a residual of the main paper roll supported by the main paper roll support; and a setting unit for setting the spare paper roll according to the residual of the main paper roll detected by the residual sensor.
In a second aspect of the invention, there is provided a paper roll support apparatus for a printer, comprising: a main paper roll support for rotatably supporting a main paper roll; a paper feed unit for unrolling the main paper roll and feeding the paper; a printing unit for printing a balance report on the paper unrolled and fed by the paper feed unit; a spare paper roll support for supporting a spare paper roll and located behind the main paper roll support; a spare paper roll sto
