    • According to an aspect of the invention, an image reading apparatus includes a substrate, light emitting elements, a catoptrics system, an imaging lens, a lens position fixing unit, and a reflective surface fixing unit. The plurality of light emitting elements is arranged on the substrate in a line and emits light to a surface of an object to be irradiated. The imaging element is disposed on the substrate and receives light reflected from the surface of the object. The first optical system guides the light emitted from the light emitting elements to the surface of the object. The second optical system guides the light reflected from the surface to the imaging element. The second optical system includes a catoptrics system including a first reflective surface and a second reflective surface so that light reflected from the first reflective surface is reflected to the substrate, and an imaging lens.

    • A transmitter for use with a fire alarm system controls the monitoring of devices to be controlled based on a control command transmitted from a receiving section such as a fire receiver. With this transmitter, even if there is a short circuit in control lines for connecting the transmitter and the devices, it is not necessary to exchange fuses, and it is also possible to avoid the waste of power consumption which would otherwise incur during the actuation operation of the device(s). When the short circuit is recovered, the transmitter is able to correctly actuate the device(s). A small reverse current is permitted to flow in the control lines so as to enable the monitoring of a short circuit in the control lines by the transmitter. When the transmitter receives an actuation command from the receiving section, and if a short circuit in the control lines is detected, the transmitter goes into a standby state in which it holds an actuation signal for actuating the device(s) from being output to an actuating section. When the short circuit is recovered, the transmitter outputs the actuation signal to the actuating section.
    • 与火灾报警系统一起使用的发射机根据从诸如火灾接收器的接收部分传送的控制命令来控制要控制的设备的监视。 对于该发送器,即使在用于连接发射器和设备的控制线路中存在短路,也不需要更换保险丝,并且还可以避免在致动操作期间将产生的功耗的浪费 的设备。 当短路恢复时,变送器能够正确地启动设备。 允许小的反向电流在控制线中流动,以便能够通过发射器监视控制线路中的短路。 当发射机接收到来自接收部分的致动命令时,并且如果检测到控制线路中的短路,则发射机进入待机状态,在该状态下,其保持用于致动设备的致动信号以输出到 致动部分。 当短路恢复时,发射器将致动信号输出到致动部分。
