Abstract

PROBLEM TO BE SOLVED: To facilitate scanning and to accelerate it by booting from low power consumption standby when a time that is preliminarily set arrives when an original platen thick plate is opened, when an original is set, and when a call signal is received and off-hooked. SOLUTION: A power supply 22 consists of a standby power supply part and a main power supply part, and a main power supply part feeds a circuit which does not need power supply at the time of standby of a recording part 24 and a motor, etc., of a read system. When start factors such as transmission, receiving, copy, etc., do not occur at a preliminarily defined time, a CPU 1 stops feeding from the main power supply part and shifts to a low power consumption standby state by feeding the CPU 1 and its peripheral system control. circuits from the standby power supply part. For instance, when a user opens an original platen thick plate, which is detected by a sensor that consists of a photo interrupter, and the CPU 1 makes the main power supply part output supply because the CPU 1 decides that it is a start of copy.

Next, the ES in this facsimile machine
S will be described.

[0032] ESS stands for Energy Save S
Standby stands for low power consumption standby.

Hereinafter, based on the flowchart of FIG.
The procedure for shifting to ESS will be described. The selection of standby and ESS is performed by mode selection using a software switch.

When the software switch is set to ESS (S2), when there is no factor for activating the system after a series of operations such as transmission, reception and copying (hereinafter referred to as activation factor) for a predetermined time (S3, S4) ), The system automatically shifts to the ESS state. The predetermined time is set in advance from the operation unit.

The starting factors include a pressure plate open and a calling signal (C
Incoming call I), incoming non-ringing call signal (FC) coming from the facsimile communication network, coming in timer output signal, telephone hookup, document present, start when pressing start switch (ESS key) on operation panel I do.

If there is no activation factor for a predetermined time after being set to ESS, the following operation is performed. First, the CPU 1
Recognizes the setting of the ESS from the setting value of the software switch. If it is set to ESS and there is no activation factor for a predetermined time, it shifts to ESS,
An ESS reset signal is output (S5). Next, the main power supply supplied to the recording unit 24 is turned off by controlling a remote signal of the power supply 22 (S6).

Next, an oscillation circuit other than the system clock,
For example, OSC52 of modem 9 and OSC50 of UNK6,
Oscillation circuits that form timing, such as the OSC 54 of the LCD 13 and the OSC 54, stop oscillation under the control of the CPU 1 (S
7). Next, since the modem of the modem unit 8 has the sleep mode function, it is set to the sleep mode. In the vicinity of the other CPU 1, the IC supplying + 5VS and having the sleep mode is controlled to the sleep mode (S8).

Next, the CPU 1 executes a STOP instruction,
Next, the drive clock of the CPU 1 oscillating by the oscillation circuit of the CPU 1 is stopped, and the system enters the ESS state (S
9). At this time, the output port for controlling the relay output from the CPU 1 or the parallel I / O, the remote control of the power supply, the pseudo call signal, and the like is stopped while maintaining the state before the execution of the STOP instruction. The data bus and the address bus of the CPU 1 and the peripheral IC are pulled down by high impedance or resistance and become low level, and shift to ESS.

Next, a procedure for starting from the ESS at the time of copying will be described.

To start up from ESS, start up when a start factor is applied (S10, S11). The activation factors include the opening of the pressure plate, the presence of a document, the calling signal (CI), the facsimile calling signal (FC), the hook-up of the handset, and the ESS.
For example, pressing a key.

There are two copy modes: copy of a sheet document and copy of a book document. FIG. 2, FIG.
FIG. 2 is a perspective view showing an operation state of the facsimile machine in this case, FIG.
FIG. 3 shows the state of copying a book document.

When the facsimile apparatus is ESS, in order to copy a book document, an operation of opening the pressure plate 30 in FIG. 3 is performed. The pressure plate opening / closing sensor 31 detects that the pressure plate 30 is open.

On the other hand, in the case of copying a sheet document, in FIG. 2, when the document is set on the sheet document table 34, the presence or absence of the document is detected by the sheet document detection sensor 35. By detecting that the pressure plate is opened by the pressure plate open / close sensor 31, an NMI (non-maskable interrupt) is applied to the CPU 1.

That is, the CPU 1 sets S
The clock is stopped by executing the TOP instruction, and the apparatus is in a stationary state. Then, the return from the rest state of the CPU 1 is performed by the NMI
The STOP instruction is canceled by the input of, and the apparatus enters a standby state. At this time, the recording unit 24 performs an initial check of the laser scanner to confirm that there is no abnormality.

The pressure plate opening / closing sensor 31 uses a photo-interrupter, and the current of the photodiode of the photo-interrupter flows through the photodiode at the timing of detecting the opening / closing of the pressure plate 30.

When the CPU 1 starts up, control is performed in the reverse procedure of the transition to the ESS described above. First, the peripheral I of the CPU 1
C or the modem from sleep mode (S1
2).

The main power supply of the power supply 22 is output by controlling a remote signal (S13). Also, the oscillator 50,
51, 52, 53 and 54 are activated (S14). Further, the ESS reset signal is released (S15).

When the main power supply is turned on, the recording unit 24 checks each part of the laser beam printer (S16). For example, check that the laser scanner motor rotates normally by rotating it. Then, if there is no activation factor (S17, S18), the state is kept in the standby state.

On the other hand, since the CPU 1 does not recognize the cause at the time of starting with the NMI,
The activation factor is checked by sensing the input port of the FUNK6. Here, if the pressure plate opening / closing detection sensor 31 is on, it is detected that the pressure plate is open. If the document presence detection sensor 35 has a document, it can detect that the document is set on the document table 34 of the sheet document.

Here, a start button (not shown) on the operation panel 18 is pressed to start a copy operation. here,
In the case of a book copy, the original is read while the CS 21 in FIG. 3 is moved in the sub-scanning direction, image processing is performed by GENESIS7, converted into binary image data, directly sent to the recording unit 24, and direct copy is performed. .

On the other hand, in the case of a sheet document copy, the document set on the sheet document table 34 shown in FIG. 2 is read while moving in the sub-scanning direction. The following is the same as the book copy operation.
