ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a laser apparatus for irradiating an object to be irradiated with a laser beam.
2. Description of Related Art
As a laser apparatus for irradiating an object to be irradiated with a laser beam emitted from a laser source, there is a laser treatment apparatus that irradiates an affected part of a patient with a treatment laser beam to treat the affected part. Such the laser apparatus is so configured as to have two operating statuses; an irradiation-ready status (hereinafter referred to as a READY mode) in which laser irradiation is enabled when a laser irradiation start signal (a trigger signal) is entered and a standby status (hereinafter referred to as a STANDBY mode) in which laser irradiation is locked even when a laser irradiation start signal is entered.
The two operating modes can normally selectively be switched at the push of predetermined keys on a control panel. Accordingly, in switching from the READY mode to the STANDBY mode, an operator must search and push an appropriate key for switching to the STANDBY mode from among many keys on the control panel. This would be troublesome to the operator. In an emergency where operators and assistants have to quickly react, particularly, it would be difficult for them to promptly search and press an emergency stop button and the key for switching to the STANDBY mode.
SUMMARY OF THE INVENTION
The present invention has been made in view of the above circumstances and has an object to overcome the above problems and to provide a laser apparatus capable of correctly easily switching from a READY mode to a STANDBY mode.
Additional objects and advantages of the invention will be set forth in part in the description which follows and in part will be obvious from the description, or may be learned by practice of the invention. The objects and advantages of the invention may be realized and attained by means of the instrumentalities and combinations particularly pointed out in the appended claims.
To achieve the purpose of the invention, there is provided a laser apparatus for irradiating an object to be irradiated with a laser beam emitted from a laser source, the laser apparatus including: a display serving as display means provided with a screen for displaying laser irradiation conditions, the display being a touch panel type capable of detecting a touch position on the screen; input means for inputting a signal to start laser irradiation; mode selection means for selecting one of an irradiation ready mode of enabling the laser irradiation when the signal is input from the input means and a standby mode of locking the laser irradiation even when the signal is input from the input means; and control means for controlling the laser irradiation in accordance with the mode selected by the mode selection means, and locking the laser irradiation when detects a touch within a predetermined area on the screen of the display during the laser irradiation.
