Abstract

According to an image forming apparatus, a simple arrangement is used to switch the transmission of drive forces, produced by drive sources that are used in common by multiple drive mechanisms, without depending on the movement of a carriage, for example. The drive force produced by an LF motor to drive feed rollers is transmitted to a pump cam in a recovery system via a pendulum drive force transmission mechanism, which is provided at one end close to the feed rollers. And the drive force produced by an AP motor to drive paper supply rollers is transmitted via the same pendulum drive force transmission mechanism to the paper supply rollers, or to a blade holder and a cap holder in the recovery system. Therefore, the transmission of the drive forces can be switched by controlling the rotational directions of the motors.

Dependent claims

An image forming apparatus, which employs a recording head to record data on a recording medium, comprising:

recovery means for maintaining the recording performance of said recording head;
a first drive source for driving feeding means for said recording medium;
and
a second drive source for driving supply means for supplying said recording medium to said feeding means,
wherein said first drive source also serves as a drive source for a first drive mechanism in said recovery means by using a switching mechanism for changing the transmission of a drive force in accordance with a change in the operating direction of said first drive source, and
wherein said second drive source also serves as a drive source for a second drive mechanism in said recovery means by using a switching mechanism for changing the transmission of a drive force in accordance with a change in the operating direction of said second drive source.
