With respect to Figure 4, the battery/memory module 9 is located in two separate locations, viz. That is, it can be considered to be divided into an electricity supply area 20 and a memory area 21. memo The memory area 21 is used to transfer data from memory to the main logic board 11. There is a supervisory processor 22 used for monitoring. memory and main logic board In order to simplify the communication between the processing units 13, the supervisory processing unit 22 It is more convenient to have the same one. That is, it is a Hitachi HD64180 processor chip. It is a pool.

The supervisory processor 22 provides considerable intelligence to the memory area 22 and provides serial communication links. 14 and the main logic board 11. This reduces the possibility of injury. Reduce the number of auxiliary components associated with the supervisory processor 22. In order to eliminate memory mapping, the complete address space of the processing unit 22 It is done in a basic way using . The processing unit has four fields of memory It is designed to address a code or block. One address block ROM 23 used to store monitoring routines performed by the management device 22; and is reserved for RAM24.

The remaining three address blocks of processing unit 22 store inventory and sales data. used for The first two of these blocks are static RAM ( SRAM) devices 25, 26. Last address block Normally, I leave it as is, but if necessary, I use another SRAM or EFROM module fl127. It can also be used to address. SRAM or EPROM27 is the main logic It can also be used to replace EPROM 19 on board 11.

The electrical supply area of the battery/memory module 9 is 24 volt rechargeable. Controls the supply of electricity to other parts of the recording device via the power supply 28 and power lines 30.31 It includes a control and monitoring circuit 29 for monitoring and monitoring. Power line 30.31 and direct The column contact wire 14 is connected to the battery/memory module inserted into the housing 3 at the bottom. When installed, connect to other parts of the recording device via a 5-way connector. power supply 2 8 consists of two series 12V, 0.8Ah sealed lead acid batteries, with short Control system that provides circuit protection and shutdown function when the output voltage drops below a predetermined value. and the monitoring circuit 29.

Thermal printers draw 5 to 7 amps for about 5 milliseconds when printing a solid black line. 24 volt battery positive so that it can carry high current pulses of Rails are required. However, this may be a drain on the battery during normal operation. This is the biggest demand for deaf people.

It is an accident to provide a power source with a low impedance for this requirement without some protection. poses a serious risk of damage to parts of the recording device in the event of a short circuit caused by Ru. The control circuit 29 is therefore a real short 7 ampere caused by the printer. 30-40 of the obviously longer time caused under paired pulses and short-circuit conditions Designed to differentiate amperage requirements.

FIG. 5 shows the control and monitoring circuit 29 in detail. a given maximum value is reached. The current from the battery increases until The maximum current is based on transistor 36. determined by the voltage drop across the parallel resistors 32-35.

These resistors are typically 1 ohm or less, and the bonds connecting these resistors are The resistance of the copper track contributes to the actual voltage drop seen across transistor 36. ing.

As the current carried by battery 28 increases by about 6 to 7 volts, the voltage The drop increases to about 0.55 volts as well, making the transistor work. Tiger When the transistor 36 (MOSFET) activates the transistor 37, the voltage decreases. To increase. In order to prevent the transistor 37 from being destroyed by electricity, a resistor is installed. device 38 switches on transistor 37 when the voltage drop exceeds relatively safe working limits. It is designed to stop functioning. Safe working limits are 0°5 volts and 3. Between 5 volts is typical, due to the current flowing through the MOSFET (MOSFET) run transistor.

the trickle current to supply electricity to the control processor and memories 25-27; MO3FET transistor 39 and resistor 40 connect resistor 32 to 35 and transistor 37 in parallel. Resistor 40 is typically 500 ohms This causes the current flowing through transistor 39 to typically be less than 50 amperes. There is. Once the cause of the short circuit is removed, current can flow through transistor 37 again. Yes, and the recording device works normally.

Electricity is passed directly from the battery to the main logic board 11, providing a 24 volt power supply. The 5 volt power supply is converted to a 24 volt power supply by a voltage conversion circuit on the main logic board. It is made from. The 5 volt power supply is for the logic circuits on the main logic board 11. Part of it is used to supply electricity to the display 5 and printer 8. 5bo The root power supply is also connected to battery/memory module 9 via line 40 in FIG. used to power the low voltage logic of the control and monitoring circuit 29. It will be done. Of course, there is no need to include a voltage conversion circuit inside the battery/memory module. There's no reason not to. Convenience when designing circuit board layouts Its exact location is determined by the point .

The control and monitoring circuit 29 virtually prevents the battery 28 from being completely discharged. By making it possible, data in memory is completely protected. ing. If the output voltage from the battery is greater than approximately 16-17 volts, the transformer The resistor 41 is actuated by the voltage across the resistors 42, 43 and the voltage across the transistor 37. ．． 39 also works. However, if the battery voltage is more than about 16-17 volts If the voltage across resistors 42 and 43 becomes low, the voltage across resistors 42 and 43 becomes decreases to levels insufficient to maintain channel conduction. and the transition Stars stop working. Transistor 41 stopped working. The transistors 37 and 39 also stop working, which causes the battery to discharge faster. Prevent them from proceeding further. Normally, the electricity remaining in the battery 28 will drain the battery Please note until charging or other power source is available to facilitate data retrieval. is sufficient to maintain all the data stored in the

If the original module's battery is depleted as described above, the other battery/memory To enable the memory module battery to supply electricity to the recording device. A flying conductor is provided within the housing. The flying conductor is at one end Fits into the female connector on the body of the battery/memory module It has a male connector. The other end of the flying conductor is the main logic board is connected to. Therefore, a voltage change is required to convert 24 volts to the above 5 volts. provided to the switching circuit.
