Description

DETAILED DESCRIPTION OF THE INVENTION 1. Field of the Invention The present invention relates to a recording device such as a copying machine or a facsimile machine, and more particularly to a recording device in which each component is controlled by a microcomputer or the like.

■Conventional technology For example, some types of copying machines are equipped with microcomputers and various sensors to perform copying processing under program control while monitoring the status of each component. Data indicating the cumulative number of copies etc. is stored in the storage means. Some copying apparatuses of this type display such data on a copy number display in response to predetermined operations.

In this way, there have been copying devices that can call up simple data, but since this function was provided for the purpose of collecting market data, it is difficult to correctly evaluate the operation of the control system from this data. I couldn't. For example, the occurrence of a jam can be detected using two or more sensors spaced apart from each other in the paper feed path, provided that these sensors are operating correctly. However, in the past, a measuring device such as a tester or a synchroscope was required to evaluate the operation of the sensor.

(Objective of the Invention) An object of the present invention is to provide a recording device that can easily and easily confirm arbitrary information stored in a storage means.

■Structure of the Invention In order to achieve the above object, the present invention provides a numerical input means for inputting numerical information of 0 to 9; a recorded information input means for inputting at least two different recorded information; In a recording device comprising a numerical display means for displaying numerical values; a control means for controlling each component; and a storage means for storing at least control information related to control performed by the control means: Instructing to set a read mode. The control means is provided with an instruction means, and the control means sets a read mode in response to an instruction from the instruction means, and while setting the read mode, the storage contents of the storage means corresponding to arbitrary numerical information inputted from the numerical input means are set. shall be displayed on the numerical display means.

For example, a copying machine is equipped with numeric keys for specifying the number of sheets to be recorded and a display for displaying the number of sheets to be recorded.

That is, according to the present invention, the contents stored in the storage means can be easily and easily checked without changing the hardware.

In addition, since the detection information of the sensor, etc. is written in the area of the storage means specified by a predetermined address, by calling up that information, the detection information of the sensor, etc. operation can be evaluated, making maintenance easier.

Furthermore, during the read mode setting, the numerical information is updated to a high value in response to one input of the record information input means, and updated to a low value in response to another input different from that input, thereby increasing the memory value. It becomes easier to recall information stored in the device. In this case, the device is equipped with a key switch that updates the recording magnification higher and a key switch that updates the recording magnification lower.
Predetermined recording information is updated in opposite directions, such as a key switch that updates the recording density higher and a key switch that updates it lower, or a key switch that updates the recording position in the positive direction and a key switch that updates the recording position in the negative direction. Using a pair of switches increases operability and prevents errors.

FIG. 4 shows a memory map of the device of this embodiment.

In other words, 56 bytes from addresses 0000 to DFFF are in the program memory (ROM) area, 2 bytes from addresses E000 to E7FF are in the data memory (RAM) area, and 6 bytes from addresses E800 to FFFF. They are respectively allocated to the Ilo area.

In the device of this embodiment, any address in these memories can be specified using the numeric keys 23, and the data written there can be displayed on the sheet number display 26. This function is shown in Figure 5 below.

This will be explained with reference to FIG. 6, FIG. 7a, FIG. 7b, FIG. 7C, and FIG. 7d.

The flowchart shown in FIG. 6 is the main routine of the main CPU 1. When the main CPU is powered on, it initializes each component, register, memory, etc., sets a standard mode (standard copy mode), and then performs loop processing until the power is shut off. This process varies widely.

The process can be broadly divided into the process of creating a copy selected according to the setting/resetting of the flag FADD, and the process of displaying the memory contents.

The flag FADD is set/reset in subroutine 5.
It is set in B100.

Please refer to the flowchart shown in Figure 7a.

In this subroutine 5B100, the JS key 20
When the and # keys 22 are operated simultaneously, the flag FADD is set, and when the JS key 20 and the C key 21 are operated simultaneously, the flag FADD is reset. When flag FADD is set, N register (internal register)
and reset the flag Fist.

In this case, in order to prevent duplicate reading due to key operation, the key-on rising is a condition (the same applies hereinafter).

When flag FADD is set, subroutine 5
Run BIIO, 5B120 and 5B130.

This subroutine 5BIIO, see the flowchart shown in FIG. 7b, reads an input specifying a memory address. As mentioned above, the memory address is represented by four hexadecimal digits, but each hexadecimal digit is converted into decimal during input. The conversion table is shown in Table 1 below.

Table 1 In other words, the memory address is entered as an 8-digit decimal value.For example, if the address is (E 50 B), (
(1,4), (0,5), (0,0), (1,1
)) becomes.

In concrete processing, first, the value of the N register is checked, and if the value is 3 or less, the numerical data (BCD) corresponding to the operated numerical key is stored in accumulator A (internal register). After that, when the flag Fist is reset, the upper 4 bits of the memory specified by the address DBDG''N'' indicated by the value of the N register are
Store the data of accumulator A in t and set the flag Fi.
Set st.

When the flag Fist is set, the data of the accumulator A is stored in the lower 4 bits of the memory specified by the address DBDG''N'' indicated by the value of the N register, the flag Fist is reset, and the N register is set to 1. Increment. In other words, for example, when the value of the N register is 1 and the flag Flst is set, the lower 4 bits of the memory specified by the address DBDGI
Store the data of accumulator A in , and set the flag Fis
Reset t and update the value of the N register to 2.

When the above steps are repeated until the value of the N register becomes 4, the process returns to the main routine. At this time, address DBDG
BCD data at an address designated for reading is written into the memory designated by O to DBDG3.

Upon completion of subroutine 5BIIO, subroutine 5B120 shown in FIG. 7C is executed.

In this case, the value of the N register is 4 or less, that is, 4
When , the value of the N register is incremented by 1 (+1
), converts the BCD data stored in the memory specified by address DBDGO to binary data and converts it to the upper 4 bits of memory specified by address DBADD1.
t and converts the BCD data stored in the memory specified by address DBDGI into binary data and stores it in the lower 4 b of the memory specified by address DBADDI.
Convert the BCD data stored in it and the memory specified by address DBDG2 into binary data and convert it to the top 4 of the memory specified by address DBADDO.
bit, converts the BCD data stored in the memory specified by address DBDG3 to binary data, and converts it to the lower 4 of the memory specified by address pBADDO.
Store in bit.

Furthermore, address DBADDO and address DBAD
The data in the memory specified by Dl is stored in the HL register (internal register), and the value of the HL register and the data in the memory specified using it as an address are transferred to a display flow (not shown). As a result, when the display flow is executed, the magnification display 2 provided on the operation board 11
7 is displayed, and the data in the memory specified by the address is displayed on the sheet number display 26. At this time, since the magnification display 27 is a 3-digit display, the lower 3 digits of the input address are displayed, but in the display flow (not shown), the lower 3 digits are displayed and the upper 3 digits are displayed. It is possible to switch. In other words, in the display flow, if the density adjustment key 28 is operated while the lower 6 digits are displayed, the display is shifted to the left and switched to the upper 3 digits, and when the upper 6 digits are displayed, the density When the adjustment key 29 is operated, the display is shifted to the right and switched to display the lower three digits.

FIG. 5 shows address DBADDO and address DBA.
This diagram schematically shows a mode in which the data in the memory designated by DD1 is stored in the HL register, and the display driver DD provided on the operation board 11 is driven by the data in the designated memory using the value as an address. In addition, DBDGO to DBDG3 and DBADDO, DBAD shown here
The memory area specified by DI is a RAM area.

In the subroutine 5B130 shown in FIG. 7d,
The address input in response to the operation of the ZU key 24 or ZD key 25 is updated.

That is, when the ZU key 24 is operated, the data in the area specified by the address DBADDO is incremented by 1 (+1)L at the rising edge of the key, and when the ZD key 25 is operated, the data specified by the address DBADDO is incremented by 1 at the rising edge of the rising edge. Decrement the data in the area by 1 (-1). However, if the data in the area specified by address DBADDO is incremented by 1 and its value becomes "00", the data in the area specified by DBADDl is incremented by 1, and the data in the area specified by address DBADDO is incremented by 1. When decremented, the value becomes “FF”
”, the data in the area specified by DBADDI is decremented by 1.

After this, when subroutine 5B120 is executed, the value of the N register is 5, so the updated address D
The data in the memory specified by BADDO and address DBADD1 is stored in the HL register, and the next address and its corresponding data, or the previous address and its corresponding data are displayed on the display 27.26. In other words, the address entered by operating the numeric keys 23 can be successively incremented by 1 using the ZU key 24 or decremented by 1 using the ZD key 25.

In the above-described embodiment, the ZU key 24 and the ZD key 25 are used to update the input address, but the present invention is not limited to this, and any key switch may be used. However, a pair of the ZU key 24 which updates the magnification to a higher value and a ZD key 25 which updates the magnification to a lower value, or a pair of the density adjustment key 28 which updates the density to a higher value and a density adjustment key 29 which updates the density to a lower value, By using a set of key switches for inputting mutually contradictory recorded information such as , etc., operability is improved and input errors can be prevented.

■As described in detail of the invention 1 According to the present invention, for example, the hardware can be changed by using a numerical key for specifying the number of copies and a display for displaying the number of copies, which are provided in a copying device. Any stored content of the storage means can be easily and easily confirmed without having to do so.

In addition, during the read mode setting, the numerical information is updated to a high value in response to one input of the record information input means, and updated to a low value in response to another input different from that input. This makes it easier to recall information stored in the storage means.

In this case, the device is equipped with a key switch that updates the recording magnification higher and a key switch that updates it lower, a key switch that updates the recording density higher and a key switch that updates it lower, or a key switch that updates the recording position in the positive direction and a key switch that updates the recording density in the negative direction. Using a pair of switches that update predetermined recorded information in opposite directions, such as a key switch that updates the information in opposite directions, improves operability and prevents errors.

Therefore, for example, by calling up the detection information of the sensor, etc. written in a predetermined area of the storage means, the operation of the sensor, etc. can be evaluated without the need for a measuring instrument such as a tester or synchroscope. Maintenance becomes easier. Further, even when it is necessary to depack a program during development or the like, side effects such as being able to depack without using a dedicated program depacking device can also be obtained.
