Abstract: PURPOSE:To obtain a current-carrying recording apparatus achieving reduction of the number of protecting resistances and miniaturization of a driving circuit by driving recording electrodes in the time sharing manner and forming blocks each consisting of said recording electrodes of the number of the time division which are not driven simultaneously, and using a protecting resistance in common in each block. CONSTITUTION:Recording electrodes 2a-2d are gathered by the number of the time division which are not turned conductive simultaneously. This group of recording electrodes 2a-2d is made one block driven in four divisional manner. A transistor selected by a signal input to input terminals 8a-8d of time-divided driving signals among transistors 4a-4h is driven by a recording signal input to input terminals 9a-9d. A protecting resistance 6a is provided so as to protect the driving circuit. Since the recording electrodes 2a-2d are driven by the time sharing method, a current running in the protecting resistance 6a is always equal to a current between one of the recording electrodes 2a-2d and a return electrode 1. Accordingly, the protecting resistance 6a can be used in common for the recording electrodes 2a-2d, so that the number of the protecting resistances can be remarkably reduced, and the driving circuit can be rendered small in size.

Title: Theft preventing device for vending machine
Inventor: ISHIDA TAKESHI
IPC: G07F9/00
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To obtain a clue to specify or arrest an offender by controlling the stop of recording on image memory based on a signal of a sensor that detects that a vending machine receives damage. SOLUTION: A controlling means 4 decides an emergency state and a normal state that is not an emergency state based on a signal from an emergency state detection sensor 3. When the means 4 decides that an emergency state occurs, i.e., a vending machine 5 receives damage, it stops writing a video signal that is outputted from a video camera 1 on image memory 2a. That is, it makes the memory 2a a write inhibition state. In such cases, the memory 2a stores images of, e.g. 64 frames before and after the emergence state occurrence. Because the images recorded on the memory 2a can have an image that picks up an offender, it can help specify or arrest the offender as a useful clue.

Abstract: PURPOSE:To avoid complication of an optical system and make it possible to detect signals at high S/N by providing a device that separates reflected light into plural luminous fluxes of different state of polarization and dividing a photodetecting part into plural photodetecting faces. CONSTITUTION:Reflected luminous flux from a recording medium 24 passes through an objective 23 again, and reflected by a beam splitter 22 and passes through a 1/2 wavelength plate 25.

Supposing that the signal outputted from photodetecting faces A-F are IA,IB,IC,IE,IF respectively, when the recording medium 24 gets away from the objective 23, the light spot becomes small, and consequently, IC,ID become large and a focus error signal takes negative value. When the recording medium 24 becomes more distant, the light spot on the photodetecting part becomes large, and consequently, the focus error signal takes positive value.
