Abstract
Abstract An image processor including a memory for storing bit images of a graphic pattern or a character, a receiver for receiving information regarding an image to be outputted from an external apparatus, and an image writer for writing bit images on the memory in accordance with the received information. A timer is provided and starts to clock when the image writer begins to write bit images. A control circuit is also provided for forcibly stopping the operation of the image writer if the imaging operation by the image writer has not yet been completed upon the timer reaching or exceeding a predetermined period. The predetermined time period is determined in accordance with the bit images being a graphic pattern or a character.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
120 words
An image processor which receives data indicating particular characters and/or graphic patterns and which converts the data into bit images of actual dot patterns to be outputted to an external apparatus, comprising: memory means for storing said bit images; imaging means for conducting an imaging operation in which the received data is converted into bit images and for writing the converted bit images into said memory means; timer means for clocking a predetermined time period from a time when said imaging operation is started; and control means for forcibly stopping the imaging operation of said imaging means if the imaging operation has not yet been completed at a time when said timer means reaches or exceeds said predetermined time period.
Claim 2
Dependent Claim
120 words
An image processor which receives data indicating particular characters and/or graphic patterns and which converts the data into bit images of actual dot patterns to be outputted to an external apparatus, comprising: memory means for storing said bit images; imaging means for conducting an imaging operation in which the received data is converted into bit images and for writing the converted bit images into said memory means; timer means for clocking a predetermined time period from a time when said imaging operation is started; and control means for forcibly stopping the imaging operation of said imaging means if the imaging operation has not yet been completed at a time when said timer means reaches or exceeds said predetermined time period.
Claim 3
Dependent Claim
40 words
An image processor as claimed in claim 1, further comprising means for setting the predetermined time period to be clocked by said timer means in accordance with a particular type of bit image to be written in said memory means.
Claim 4
Dependent Claim
37 words
An image processor as claimed in claim 2, wherein said time period is determined according to whether the type of said bit image to be written in said memory means is a graphic pattern or a character.
Claim 5
Dependent Claim
74 words
An image processor as claimed in claim 1, wherein said imaging means comprises: a font memory in which respective bit images of characters are stored and from which a particular bit image is read according to the received data, and a character imaging means for reading said bit image of a character from said font memory according to the received data and for writing said bit image of a character into said memory means.
Claim 6
Dependent Claim
24 words
An image processor as claimed in claim 4, wherein said timer means is started every time the imaging operation of one character is started.
Claim 7
Dependent Claim
37 words
An image processor as claimed in claim 4, wherein said imaging means further comprises graphic imaging means for forming a graphic bit image on said memory means according to the received data which indicate a graphic pattern.
Claim 8
Dependent Claim
96 words
An image processing method comprising the steps of: receiving data which indicate particular characters and graphic patterns and which will be converted into bit images of actual dot patterns to be outputted to an external apparatus; conducting an image operation in which the received data is converted into bit images; writing said converted bit images into a memory; timing a predetermined time period from a time when said imaging operation is started; and stopping the imaging operation if the imaging operation has not yet been completed at a time when a predetermined time period is achieved.
Claim 9
Dependent Claim
96 words
An image processing method comprising the steps of: receiving data which indicate particular characters and graphic patterns and which will be converted into bit images of actual dot patterns to be outputted to an external apparatus; conducting an image operation in which the received data is converted into bit images; writing said converted bit images into a memory; timing a predetermined time period from a time when said imaging operation is started; and stopping the imaging operation if the imaging operation has not yet been completed at a time when a predetermined time period is achieved.
Claim 10
Dependent Claim
50 words
An image processing method as claimed in claim 7, further comprising the step of setting the predetermined time period at a first value when the bit images correspond to a graphic pattern, and setting the predetermined time period at a second value when the bit images correspond to a character.
