The cover 80 is configured to be openable and closable with respect to the apparatus main body 1 around the hinge portion 80a. When the cover 80 is opened, the cover 80 is within the reciprocating movement area of the carriage 30 (including the ink cartridge 31) and outside the paper passing width area. An opening 90 necessary for replacing the ink cartridge 31 (or ink tank 31b) is formed. Normally, the carriage 30 is positioned at the home position and is waiting for a recording operation. The home position is provided with a maintenance mechanism for performing cleaning and capping of the printer head 31a, preventing dust from adhering to the printer head 31a, preventing ink clogging, preventing ink evaporation, and the like. ing. As a result, the state of the printer head 31a is always kept good, and a stable recording image quality can be obtained. Therefore, if the operator can easily touch the carriage 30 at the home position and the mechanism for maintenance, it is not preferable to maintain high image quality, for example, sufficient maintenance cannot be performed. In view of the above, in this embodiment, the home position is arranged on the right side of the moving area of the carriage 30, that is, on the right side of the apparatus, and the operator carelessly touches the waiting carriage 30 (ink cartridge 31). This prevents the deterioration of image quality.

  When replacing the ink cartridge 31 or the like, the cover 80 is opened, a replacement button (not shown) provided in the apparatus is pressed, and the carriage 30 waiting at the home position is moved to the left side of the apparatus where the opening 90 is located. The ink cartridge 31 and the like can be accessed from 90, and a desired replacement operation is performed.

  The opening 90 is formed below the handset 8 and is configured to open and close the cover 80 while leaving the placement portion of the handset 8. For this reason, even if a call is received during ink tank replacement, the handset 8 can be picked up and answered without any problem.

Since the maintenance unit 38 is in the standby position of the carriage 30, it needs to be provided outside the sheet passing area. For this reason, the right end side of the reciprocating area of the carriage 30 is used as a standby position, the left end side is used as an ink cartridge 31 replacement position, and the standby position is configured so that the operator cannot easily access it. The ink cartridge 31 can be replaced on the side opposite to the position. The document transport path 45 is disposed above the recording paper transport path 37 and on the right side of the apparatus at a position that does not interfere with the replacement position of the ink cartridge 31. The document conveyance drive system 58 is arranged in the space on the left side of the recording sheet conveyance path 37 and the document conveyance path 45 on the front side of the recording unit 3 to increase the efficiency of space utilization of the apparatus. Further, the cover 80 is provided at a position where the handset 8 is disposed above the ink cartridge replacement position and the drive system 58 and does not interfere with the handset mounting portion. Thereby, the reading unit and the recording unit can be efficiently arranged, and the apparatus can be reduced in size. At the same time, it is not necessary to open the operation panel 7 for replacing the ink cartridge as in the conventional case, that is, the reading operation is restricted by opening the document conveyance path, and the display unit and buttons of the operation panel 7 are difficult to operate. Ink cartridges can be replaced without any problems. Furthermore, since the display unit can be viewed during the replacement work, the user interface can be improved by displaying guidance for the replacement work. In addition, since the cover 80 is disposed at a position where it does not interfere with the handset placement unit, there is no problem that a telephone call cannot be made during replacement work.

About the part which attached | subjected the same number, description is abbreviate | omitted as having the same function and a function. Reference numeral 81 denotes a cover that can be opened and closed in the direction of the arrow X with respect to the apparatus 1. The cover 91 is slid in a direction away from the apparatus to form an opening 91 for replacing an ink cartridge or the like. The cover 81 also serves as a placement portion for the handset 8 and moves together with the handset 8 when sliding. With this configuration, the handset overlaps the ink cartridge replacement position during normal use, but the cover 81 can be moved together with the handset 8 when the ink cartridge is replaced, and the opening 91 can be formed larger. For this reason, the space where the operator puts his / her hand to work can be configured larger and workability can be improved.

  In the embodiment described above, both the document conveyance path and the recording paper conveyance path are substantially straight paths from the rear to the front of the apparatus, but the same effect can be obtained even if either one or both are U-turn path shapes.

In addition, an ink jet printer is used for the recording unit, but other methods such as a thermal transfer method may be used. If the system has a printer head unit that reciprocates in a direction perpendicular to the recording paper conveyance path, the same exchange workability effect can be obtained. Can be obtained.
